I have a HP-G64-455SX laptop.

Windows was corrupted so I decided to install Ubuntu 11.10 on it. All things were working properly but my webcam is not working.

Last time I used my webcam was 3 weeks ago.

How do I fix this error I have googled a lot but didn't find anything?

Here is the lspci output:

unless I'm missing something... I cant see the webcam in that list - possibly a USB device? what is the output of lsusb. Note - on some laptops there is a Fn key type arrangement to enable a webcam. If you dont use this, the O/S doesnt see the webcam. –  fossfreedom Jan 5 '12 at 10:56
    
updated.........no function like this –  One Zero Jan 5 '12 at 11:02

... well your connected usb devices dont correspond to webcams either. Since lsusb and lspci see hardware level stuff - I dont see in your trace logs a physical webcam on your laptop. Are you sure you havent got a hardware switch/slider to enable your webcam? –  fossfreedom Jan 5 '12 at 11:09
    
its buitin cam ...just like in every laptop ...& no other option to on/off cam ... –  One Zero Jan 5 '12 at 13:29

Apparently it is a hardware problem.

Thanks to fossfreedom!
